So in an attempt to avoid flushes on remap etc, I've attempt to avoid doing anymore than 1 cache flush per batchbuffer..
http://people.freedesktop.org/~airlied/i915-hack-cacheflush.txt I allocate the batchbuffers CACHED and then flush the cache for those pages post relocating.. I need to checkout the speedups on SMP machines as the ipi overheards are much worse there... this code is a dirty hack as it does x86 specifics in the drm, but I'm just throwing the idea out there..
